Alstroemeria plant variety named `Staprizsa`

ABSTRACT

A new and distinct Alstroemeria plant variety producing flowers of good quality and attractive coloration, suitable for growing in pots.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct variety ofAlstroemeria hybrid originated as a seedling by crossing as seed parentan unreleased, unpatented seedling identified as 91D196-1 and as pollenparent an unreleased, unpatented seedling identified as 7G1069-02 fromamong my collection of Alstroemeria seedlings maintained undercontrolled conditions in a greenhouse at Van Staaveren B.V., Aalsmeer,The Netherlands, for developmental purposes. The varietal denominationof the new variety is `Staprizsa`.

The first act of asexual reproduction of `Staprizsa` was in Aalsmeer,The Netherlands, by propagation by dividing rootstocks. Asexualreproduction in Aalsmeer, The Netherlands, through successivegenerations has demonstrated that the combination of characteristics asherein disclosed for `Staprizsa` are firmly fixed and retained throughsuccessive generations of asexual reproduction.

`Staprizsa` has not been observed under all possible environmentalconditions. Phenotypic expression may vary with variations inenvironment such as temperature, light intensity, day length and growingand cultural conditions.

SUMMARY OF THE INVENTION

Flowers of the new variety of Alstroemeria, `Staprizsa` arecharacterized by flowers of unusual coloration, as described herein. Thenew variety is especially suitable for growing in pots.
